ADDING-MACHINE.

l citizen of the United States, residing atDey 4'substantial y'Patents Numbers 504.963 and 505,078, is-

troit, in the county of Tayne and State of Michigan, have invented certain new and useful Improvements in Adding-Machines, of Which the following 1s 'a speclhcaticn.

My invention relates to adding machines and therlike of that ,type 0r character capable. oflisting, printing and adding or accumulating individualntems, such character of machine being-exemplified by the Well known Burroughs adding machine made in accordance With Burroughs Sued on September l2, 1893.V

yThe object of myfinvention is to provide I efficient 'and reliable means for automatically taking atotal by a blank operation of lao the machine without the employment of the usual total keyor button or any equivalent mechanismrequiring manipulation or setting by the operator inthe operation of tak-l ling a total (subtotal or grand total).

In the present instance, for the sake of a clear and deinite description of my invention, I have illustrated and wlll hereinafter describe my invention as embodied 1n an. adding machine ofthe Burroughs type, 'but it will be'understood that my invention is not restricted in its application or scope -to suoli particular machine, but that it may be employed 1nconnectionv with machinesv of the same general character and used for the same general purposes.

In the drawings, Figure l is an elevation of some of the principal operating parts on the right-hand side of a Burroughs adding Y machine, the parts more particularly illustrated being the ones in connection lwith which my attachments orimprovements eooperate for the purposes stated; Fig. 2a View similar to Fig.- l-but of the left-hand side of the machine; Fig. 3 a detail view of my attachments and the parts of the regular Burroughs machine directly associated therewith, such View illustrating the rel-ative position of the parts after a value key on the keyboardhas been operated or depressed;.Fi g. e a. similar detail view illustrating the relative position of parts when Y operated by a blank stroke or operation of the machine, Figs. 5 and 6 detail views of certain ofthe ,newv parts, and Figs. 7 and` 8 Specicatlon. of Letters Patent.

The Burroughs adding machine being Well-known, and illustrated and described in a number of patents and pending applications for patents, I shall here describe only those parts thereof which are assoj ciated. with and concerned in the operation of the parte which I Yhave added to the machine for the purpose of automatically taking a total'in the manner hereinafter eX- The Burroughs machine employs a series of adding wheels 912 mounted in the upper end of a rocking frame 910, Figs. 1 and 2, each provided upon its side with a pinion 916,v said pinions being adapted to coperate with racks G10 (shown in dotted lines) carried by the front-ends of levers 611 hung upon the central4 shaft 600 of the machine and carrying at their rear ends. the printing type 618 coperating with the platen roller 1599. f

The main .operating shaft of the machine, to which ower is applied, usually by means of a suita le handle, 1s the rock shaft SOO-shown in Fig; 1; and thev ordinary 0peration of the machine consists in' depressing or setting the proper number or value,- keys 291 and then yrocking said shaft for- Ward and backward through its limit of movement. Whenon'e of the keys 291, in any given denominational row, is depressed or set, and the rock shaft 300 rocked for- Ward, the rack 610 carried by the lever 611 corresponding to suoli row of keys will be released and permitted to drop downward a distance measured by the value of the operated key; and when the rock shaft is rocked backward to normal position the rack will be lifted to its normal position again and theoperated key be released.

By engaging the pinions 916 of the adding wheels with the rack 610 during the movement of the latter in one direct-ion, and holding themlout of engagement therewith during their 'movement in the opposite direction, the values of the operated keys may beV added upon said Wheels. In the Burroughs machine the adding Wheel pinions, While normally engaged with rthe racks,

" 1 .backward movement'of`the o Figs. 1 and 2, are disengaged therefrom at ,the beginning of each adding operation of the machine, andM held out of engagement with them during the downward movementof the racks, and then rengaged with them prior to their upward or return n iovement and held in engagement with them during such movement. This is accomplished by the meanbfashown inFig. 2, where it willl be seen that a'three-armed lever 913 hung u on a stud 941 has pivoted to the lower en of .its middle ,arm the rearend of a forwardly extending `arm 914which is supported near -its forward end by along link 911 h at its upper end to the front endof the crank 227 fulcrumed upon framework'in the 'machine at 204. At its front end the arm 914 is divided into -twodiverging arms, the

, upwardly extend-ing one 914:l AofI which is provided with anotch engagin a stud 958 upon one of the side arms 910 o the roc frame which carries the adding wheels. In the normal operation -of the machine, for the purpose of printing and,.accumulating individual items or amountsthe arm 914 is swungbodily forward at the beginning of each operation of the machine, to disengage kthe adding wheelpinions from'the racks,

and is swung bodily backward, to rengage them therewith, .at the beginning of t-he perating handle and rock shaft 300.v Thisis accomplished by means of a wiper plate 821, pivoted uponthe upper end of an arm 813 fast upon a rock shaft 800 which is so connected with the operating rock shaft 300, Fig. 1, that with studs 961 an rearward movement of the they move in reverse directions, the arm 4813 being swung rearward at the forward move# ment of the operating handle andy ro'ck shaft chine it is simply necessary to leave the addl ing wheel pinlons 1n mesh Ywith the racks while the latterare permitted todrop and vturn the wheels backward to zero. This will set the type carried by the rear ends of the levers 611 to position to rint Athe amount represented upon vthe addpin -wheels prior to the turning of. them bac ward to zero. If it be desired to leave the adding wheels at' zero, after taking the total, and to thus clear the machine, ions arel disengaged from the racks while in zero position, the racks then re- Afront end of the bell c the adding wheel pinturned to normal position; but if it be desired to leave in the machine the amount which had been accumulated on the adding wheels, and take onl a sub-total, the adding wheel pinions are lel in mesh with theracka during the return movement of the latter andare consequently turned forward again to the respective positions which they before l occupiedl `To permit the adding wheel inions to remain in mesh with the racks uring the downward movement ofthe latter, for the purpose of taking a total, it is necessary to swing the front end of the arm'914 down andv disengage the notch in its upper end from the stud r958 of the adding wheel frame, so that upon theforward movement of the arm 914 t e wheel frame will not be swungfo'rward as itnormally is. In the'Burroughs machine as heretofore generally constructed this depreion of the front end of the arm 914 was accomplished by means of a total ke secured to the 227, by depressing which key the arm`914 would lio-sw `'downward and disenga ed from the stu 958 on the addin rassion of the whee l Such dent end of the arm 914 rought the hooked lower end ofits lowe'r -forward arm 914' in position to engage a stud 958* upon the lower end of the side arm 910 of the adding wheel frame at the' backward or return movement of ythe arm 914, with `the result that at the beginningof the return movement, of the operating handle and `connected parts the adding wheel frame would be rocked upon its pivotal su port. 900,aad the imons disengaed m the racks, there y leaving the ad i wheels at zero while the racks return to normal position. When it was desired to take merely a sub-total, the total key was held depressedonly .during the forward movement of the operatin handle, and then released, thereby lpermitting the front end of the arm 914 to rise to normal position and'its subsequent rearward movement to havel no effect uponl the addin wheels, whose inions therefore romaine in mesh with e racks during the return upward movement of ,the latter.

. AHaving now described the usual operation of taking totals and sub-totals upon the Burroughs machine, and the parts concerned in such operations, I will roceed to an explanation of the, means w ich I have provided for automatically taking a total by a mere blank or extra handle:

The rock shaft 204 to which the bell, crank 227 is secured extends transversely through the machine and, has secured to its opposite end (Fig. 1) a depending arm 227, corresponding'to the depending arm 22T of the stroke of the operating4 hell-crank 227. Pxvoted about midway of la f hooked rear 'end of the leverv 62.7 is adapted" its lengthgupon the arm 227R is a v lever provided with a hooked rear end and albev-v eled or cam shapedA forward= end. `The torcoperate with a 'stud 663 upon the up- 4per'endY of *a bell-crankarm .626 :loosely lever with said stud. The `'short forwardly y 311*L forming in the present instance anin-y v tegral part. and rearward extension of the,4 l short sector plate 311 of the Burroughs ma-l projecting arm of the bellcrank 626 carries a roller 634, coperatingwith'a cam plate chine, fast7 upon the rock shaft- 300r The Y.plate 311'* has an abrupt shoulder at its ,'up-

per forward end, against which the roller 634l normally rests, so thatateach operation ot' the machine the bell crank 626wil1 .be

rocked and its upwardly projecting arm thrown rearward at the beginning of the movement of said yplate, the remainder of the cam `surface'or edge of the plate being approximately concentric'to' the shaft 300 so as to simply holdthe bell-crank 626 in its moved position during the further travel of the plate. It the hooked rear end of the le-A .ver 627 bein engagement withthe stud 663 on thebell-crank626 at the time .the latter is thus swung rearward, the arm 227R which carries the lever 627 will be swung rearward and thereby rock; the-shaft 204 and swing downward the forwardly project-ing arm of the bell crank 227, Fig. 2, so as to prevent the adding wheel pinions from bein disengaged from the racks by the forwar vmovement 'ot' the arm 914, as heretofore described, and thuspermit said pinions to vremain in mesh with the racks during the descent of the latter, forthe takingv o? a total. In the `normal operation of the machlne, for the purpose of accumulating and printing individual items or amounts, however, the hooked rear end of the lever 627 is maintained out of engagement, with the Stud r663, so that the rocking of the bell crank'626 has no etl'ect upon'said lever and the parts .with which itis connected. This is accom plished by means of a stud 657 carried by a bail composed oftwo vertical side arms 4211K and 42%1, Figs. 1, 2, 3 and 4, fast at their lower ends upon a rock shaft 400 and having their forwardly extended upper ends connected by a crossrod 402. This rod l02 lies immediately in rear of the downwardly bent ends 214a of the series of sliding platesr 214 of the Burroughs machine, of which plates there is one for each row of keys 291- each plate being adapted to be forced rear- Wardly by t-he depression or setting of any key in its row.` lVhen any one or more of the 'keys 291 is depressed, therefore, the bail carrying the stud 657 is swung rearwardly, and said stud, engaging and riding over the beyeled or came aped forward end ofthe lever 6.27, rocks the latter to the position Ashown in Fig.v 3 and disengag'es lits hooked rear end from the stud 663 on the bell-crank 6261.

So'long as any one or more of the 'keys 291 tis depressed, therefore, the forward.l

movement4 of the'operating handley and rock shaft 300 will have no edect upon the parts concerned in the. taking of a total and they -will remain' inert. l .Upon the first succeeding or blank stroke of the operating handle, however, the stud 663 upon the bell crank 626 would, but foritheprovision of the additionaldevices/to be now described, engage the hooked rear end vof lthe lever 627 and pull the latter rearwardyandzrock the shaft. 204 and depress the arin 914'arid leave the add* ingwheel pinions in mesh with the racks for ,the taking of a total. 'It lis considered de sirable, however, to take a spacing stroke yimmediately before taking a total, in order `to leave a slight blank space between the last item ina column and the total to be printed beneath it, and thus toseparate and distinguish the 'tota-l from such `last item;

and in the Burroughs'machine as usually sol constructed it is further necessary, to take..

such a spacing stroke for Ithe purpose' of fully restoring tonormal position anyy ofthe racks 610 which may have. been set for transfers, andthus insure a proper-acvidual items. Inasmuch as I have illustrated my present inventionl as applied to' a Burroughs' machine of this character, Iv

have provided the? additional devices, to be now described, for preventin l of the hooked rear end of theever 627`with the stud 663 upon the bell. crank 626 until after such a spacing stroke has been taken,so

sist ofa latch for holding the' bailcarrying- 100 engagement the stud 657 in its rearwardposition, as i shown in Fig. 3, during the taking of such spacing stroke; and the devices co-perating with the latch tov trip or disengageit after such stroke has been taken. This latch 628 is in the form ota bell crank pivoted at658 to a fixed plate 3-10EL in, the framework of the machine and vhaving a spring 685 connected to its short depending arm and ytending to swing its forward end downward. The front end of this latch arm` 628 is provided with a hook adapted to coperate with a stud 656 u on one of the side arms 424B of the bail w ich carries the stud 657 whichcoperates with the front end of the lever G27. 4Vhen the machine is at rest and no keys depressed the nose of the hook of-this latch restsnpon the upper surface'of the stud, as seen in ig. 1. When an'ykeyis depressed and lthe bail carrying the stud-656 95 f cumulation or adding up of all the indiin such position the stud 657 carried by said bail maintains the lever 627 in the position shown in Fi 3, with its hooked rear end disengaged m the st-ud'663 of the bell crank 626. v

The latch arm 628 is provided on its under side, about midway of its length,

with a beveled lug or projection 628` adapted to coperate with a stud 655 upon an upwardly and forwardly projecting arm 922R 'ection u on the llatc fast upon a rock shaft 904 which extends transversely through the machine and has secured to its left hand end, Fig. 2, a lever 922" whose upwardly and forwardly extending arm corresponds to the arm 922R of Fig. 1, and to the lower end of whose depending armi is connected the forward end of a link 918, whose rear end has a slot-and-pin connection with the arm or lever 813. heretofone described. Near the end of the forward movement of the operating handle and the rock shaft, and rearward movement of the arm 813, the pin or stud u on the latter will engage the rear end of t e slot in the link 918 and draw the latter slightly rear- Ward, thereby rocking the shaft 904 and swinging the stud l655, Figs. 1 and 3, upward and forward a ainst the beveled proarm 628, to lift the atter an disengage its hooked forward end from the stud 656 upon the swinging bail whose stud 657 eoperates with the lever 627. At the end of the forward movement of the operating handle and rock shaft 300, therefore, the latch 628 is disengaged from the stud 656, so that if not otherwise restrained the swinging bail would be pulled forward from the position shown in Fig. 3 by its yspring v482, and the hooked rear end .of the lever 627 permitted to rengage the stud 663 upon thebell crank 626. But under -the conditions shown in Fig. 3, where one orvmore o f the keys 291 is depressed, the swinging bail carrying the stud 657 is held rearward by the downwardly bent front ends of 011e or more of the sliding plates 204 engaging the cross rods 402 of said bail; and inasmuch as the depressed keys are 'not released in the Burroughs machine until the operating handle and connected parts have returned a considerable distance toward normal position, the latch 628 will be permitted to rengage the stud 656 (owing to the character of the slot and pin v"connection of the link 918 with the arm 913, Fig. 2,) before the depressed or set keys are released., The result will be that, while the latch 628 is lifted at each operation of the machine,-its movement is an idle one so long as any of the keys 291 are depressed,`

since it rengages the stud l656 upon the bail before the fatter is released bythe de` pressed keys. At the first blank or spacing stroke taken, however, the bail lbeing then free from the restraint imposed by any depressed keys, and being held in rearward position solely by the latch 628, the lifting of the latter will release the bail and permit its spring 482 to pull it. forward to normal position, and cause its stud 657 torelease-the lever 627 and permit the hooked rear end of the latter to engage the stud vupon the bell crank 626; and upon the next or second blank stroke the parts will be swung to the position shown in Fig. 4, and the shaft 204 be rocked to swing down the forwardlyV projecting arm of the bell crank 227, and, through the medium of the depending link 911, to depress the front end of the arm' 914 and disengage the notch in its arm 914* from the stud 958, and thereby permit the adding wheel pinions to remain 1n mesh wit-h the racks during the descent of the latter, for the taking of a total; and as the parts will be held in their moved osition, with the arm 914 depressed, unti the operating handle and rock shaft 300 have completed their forward stroke and returned nearly to normal position, owing to the travel of theroller 634 upon' the concentric surface of the cam plate 311, Fig. 4, the adding wheel frame will be rocked forward at the beginning of the return movement of the operatinghandle and rock shaft, by the engagement of the lower hooked end of the arm 914b with the stud 958, and the adding wheel pinions be thereby held out of engagement with the racks during the return of the latter to normal position, and the machine thereby cleared.

The lower ends of the two arms 227R and 227L depending from the rock shaft 204 are connected by' forwardly extending links 216 with a cross rod 209 cooperating with the latches 415 which normally hold the racks 610 in elevated position; so that whenever the arms 227 n and 227L are swung rearward in the manner above explained, for the taking of a total, all of the latches 415 are likewise swung rearward and disengaged from the racks, and all of the latter permitted to drop until their 'respective adding wheels have turned backward to zero position.4

The latches 415 are individually operated,l

to release their respective racks, inthe ordinary work of accumulating yand printing individual items, by the upturned front ends of the sliding plates 214 which are operated by the depression of the keys as heretofore explained.

In the automatic taking of a total in the manner and by the means above described the machine is cleared, that is to say, the adding wheels are left at zero owing to the fact that`their pinions are disengaged from the racks 610 prior to the return upward movement of the latter; but for the purpose of enabling a Vtotal to be taken without' clearing the machine I provide-*means for preventing such disengagement of Itheduiding wheel pinions from the racks, so that they may remain in engagement therewith during the return upward movement of the racks and be thereby turned forward again to the respective' positions -occupiedby them before the takingoliv the total. SuchA means consist in the lpresent insta-nce of a vertically sliding key or rod 221", Fig. 2, whoseloiver end, when the rod is depressed,

is adapted to stand in the path ofthe wiper plate 821 on the arm 813 ,when the latter` is swung to the rearward position shown by the dottedlines' in Fig. 2, and to depress said wiper pla-te to the position indicated by the lowermost dotted lines in said figure' so that, it will not engage the `stu`d96l on Athe three-armed-lever 913 at the return` for;I

-ward movement of the. arm 813g.'l Consequently the lever 913 will not be rocked `back t0 normal position at the return', forward movement ofthe arm 813,1and the arm 914 will not be 4drawn rearward whilein .de-v

. pressedpositiom-and its' lowerfhooked arm.

eoV

914 will not' engage the stud. 958",o`nthe adding wheelframe and rock the latter, to@ disengage the pinions from the v-racks vl For'the purpose of'detaining the key 211 in depressed `position during the operation of the machine,". and obviatingth'e necessity of holding it down by -hand,'I provide a pawluor detent 228- pivoted at 201 andl 'adapted' to engagea notch 1221" inthe rear side of thekey 221* Awhenthelatter is de.

presse'cL- a spring 285.eonx 1'ecting thejdete'ntand key serving tohold thelatter normally l elevated. The detentv is in the present instance constructedindetail as shown in Fig.

6, having a'rearwlrdlyextending arm 228 connected with-the pawl or detentproper by the ycross portion1228t, .and both arms` ofthe structure having` a bearing upon the pivot 201. A spring 288 connected toyrthe arm 228v and to a fixed part ofthemachine serves to hold the vvsaid arm down'and enforce en-V gagement of the pawl or detent 'with the notch of the key when the latter is depressed', n a function in which the spring r285 also takes part owing to its connect-ion with the detent in rear of the la'tters pivot.` The inclined or beveled rear end of they arm 228? stands in the path of the key-restoring rod or shaft 202. so that at the forward movement of the latter, near the endvo f,each'op` eration of the machine, the rear end of the arm 228b will be thrown upward and the detent disengaged .from the .key 221, to release the latter and permit it to be lifted to normal position by the spring 285. The key 221* is provided at its upper end. with a .finger button 291,"Fig. 5, an'd constitutes what iscommonlv called a sub-total key, inasmuch as by` its use a subtotal, e., a`

total withoutclearing the machine, may be' taken. y y 'f .The keyres'toringlrodi202 cooperates in fthe' well-knownA waywith `the pawls' 228,

Figs. 1 and' 2, to release the 'operatedor set 70 keysat ,the end of-eac'h operationof the Amachine,and the error key 293B, F 1, has a slotand-pn connection atits lower end with the forwardly extending arm of, one ofthe two bell cranks whichare fast' upontlie rockfshaft 207 and `carry at their upper ends thescross rod-202, so that by depressing the error keyatanytime the subtotal key 221,= as well as any operated or set number keys, maybe released. l 80 VFor the purpose of enabling the operatory to take a series of spacingstrokes at any, .time desired without operatingthe. devices foriptkinga'total I place a stud-659 upon)vv therepeat key'leverGlS, Fig, ,1, which st/ud g5 yqinderlies the hooked'lever 4627v and lifts the yrear vend of the-latter outgcof engagement. -with the stud l623 on the bell crank 626` whenever the 'repeat key 293'R is depressed.y l

Under the. construction and arrangement of partswhich have been described a grand total, or'total accompanied by a clearing of Vthe machine, is automaticall taken byj a secyond spacing stroke of the operating handle without' any preliminary operation Vor, Set- 'tingof a total key, and the latteris requiredonly where a subtotal, o r 'total unaccompanied-by afclearing ofthe'machine, is to be taken.
